Meteorological observations from airliners.

Mather, Graeme Kenneth. January 1964 (has links)
The purpose of this work is to examine the usefulness of various types of meteorological observations taken from commercial aircraft.Photographs of clouds were taken from routine flights over the southern United States. Samples of some of these pictures are presented. One set taken of a line of thunderstorms is related to a synoptic map and a U.S. Weather Bureau Radu Chart. A time-lapse sequence of convective development is examined with respect to the thermodynamic energies revealed by the appropriate radiosonde ascent. The results suggest that the freezing process is a vital source of energy in boosting the cloud tops to the heights observed. [...]

A spherical harmonic specification of the global 500 mb surface.

Steinberg, Hyman Leonard. January 1965 (has links)
During the month the zonal harmonics are well behaved and the increasing variance in the symmetric component (0, 2) reflects the seasonal strengthening of the westerlies in the northern hemisphere. In the wave regime the eccentric components with m = 1 appear to be global entities but the continuity is less obvious as one goes to higher orders. The wave subset with m = 4 exhibits an oscillation in parity such as one would expect from independent systems in the two hemispheres moving with different angular velocities. [...]

High spectral resolution gamma ray astronomy in the energy region 50keV to l0MeV

Myers, Richard Michael January 1988 (has links)
Observations of the Crab nebula region and of the unusual active galaxy NGC1275 made during a balloon flight of the Durham high spectral resolution gamma ray telescope are described. From the Crab, spectral line fluxes were detected at 79 keV (transient), 405 keV, and at 1050 keV. The first two are possible confirmation of previous results. From NGC1275, evidence of two-photon electron-positron annihilation radiation with the expected redshifted energy of 502 keV was observed. Possible interpretations are suggested.
